IMPROVEMENT IN SOLE-EDGE-BURNISHING MACHINES.

Specification forming part of Letters Patent N o. 212, 3412, dated February 18, 1879 application filed Y January 2, 1879. Y Y

To all whom it may concern.'

. Be it known that I, THOMAS P. YOUNG, of Lynn, of the county of Essex and State of Massachusetts, have invented a new and useful Improvement in Machinery for Burnishin g or Setting the Edges of Shoe Or Boot Soles; and do hereby declare the same to be described in the following Speciication, and represented in the accompanying drawings, of which- Figure l is a side elevation, and Fig. 2 a front view, of a sole-edge setting or burnishing machine embracing my invention. Fig. 3 is a vertical section ot' its reciprocating toolcarrier and its spindle, Fig. 4 being a rear view of such carrier.

My present invention may be viewed as an improvement with reference to the machine described in Letters Patent No. 195,069, dated September ll, and granted to me.

Instead of arranging the shanlredge burnisher on the same shaftwith and in rear of the tool or tools adapted toV burnish what is termed the fore-part edge of the sole, Inow arrange the shank-edge burnisher below the tool or set of tools for finishing lthe forepart edge; and I also arrange or fix the said shankedge burnisher on an auxiliary shaft, and provide such shaft with a crank to co-operate with. a furcated and slotted lever iixed on the shaft of the other tool or set of tools, all being substantially as represented in the drawings, in which- A denotes a standard or column, supporting in suitable boxes a b o d two horizontal shafts, B C, and in other boxes, e f, one of two inclined shafts, D E, arranged as shown.

The lowest of the said four shafts-viz., that marked B--is the driving-shaft of the machine, it being provided with two pulleys, t' k. An endless belt, l, extends around the pulley k, and another pulley, on, on the shaft C; and there is fixed on the front end of such shaft C a short crank, n, whose wrist enters a slot, o, in the upper arm of a lever, F, xed on the shaft D. The lower arm of the lever F is notched or furcated to receive the wrist of another crank, p, ixed on the shaft E, whose boxes or bearings are supported by an arm, q,

projecting from the standard A, and below the shaft D, in manner as represented. There is xed on the forward end of the shaft E the circular tool G, for burnishing theshank edge of a sole, a set of the other edge-finishers be; ing shown at H H H H as Vprojecting radially from a rotary carrier or wheel, I, that is sup ported on a pivot or journal, r, projecting axially from the shaft D. The hub s of this wheel is provided with four notches, t, arranged at equal distances apart, and there exA tends from the shaft D a small tooth or stud, u, to enter either of tle notches when the wheel is pressed back by a stellated spring, o, xed to the end of the pivot, and bearing against the carrier, in manner as shown.

On drawing the wheel forward and revolving it ninety degrees of a circle, and next aL,

lowing the spring to press the wheel back, we' can at any time bring and support a fresh tool into position for acting on the sole edge` On putting the driving-shaft in revolution a reciprocating rotary motion will be imparted to each of the tool-shafts, and, as va consequence, to their tools.

By having the shank-burnisher arranged below the other tool or tools, and on a separate shaft, as shown, a sole-shank, while being finished or burnished on its edge, can be seen and worked or manipulated to much better advantage than by the arrangement of such tools as shown in my said patent.

Vhat, therefore, I claim as my present in vention is as follows, viz:

1. The shank-burnisher and the fore-edge burnishing-tool carrier applied to separate shafts D E, in combination with the second ary shaft C and the two cranks n 19, and the slotted and furcated lever F, all being arranged and to operate essentially as set forth.

2. The rotary tool-carrier, notched in its hub, and the shaft thereof provided with the tooth, and the stellated spring arranged with the tool-carrier, in manner and to operate therewith as set forth.

THOMAS P. YOUNG.
